As a result, shares of Amazon ended the week up 24.3% to $118.49. Even though other retailers -- most notably Barnes & Noble ( BKS)- have rolled out e-readers, based on the company's outlook for the fourth quarter, it appears that Amazon will win with Kindle. Nintendo's Wii placed fourth at a time when video game sales and hardware have been struggling. On Monday, the NPD Group, a market research firm, said video game sales inched up 1% in September, but were still well below analysts' expectations. And sales of hardware tumbled 6% to $472.3 million. For the first time since its launch three years ago, Sony's ( SNE) PlayStation 3 was the category winner, selling more units than the Wii and Microsoft's ( MSFT)Xbox 360. Unsurprisingly, Tiffany's ( TIF) new Keys Collection came in last, garnering just 4.6% of the vote. Jewelry sales are expected to struggle this holiday season. According to the National Retail Federation, holiday sales made up 25.5% of jewelry stores' annual sales in 2008. Thus, retailers like Tiffany have even more at stake. Shares of the company slipped 1% to end the week at $41.45. -- Reported by Jeanine Poggi in New York Follow TheStreet.com on Twitter and become a fan on Facebook.
